BACKGROUND OF INVENTION

1. Field of the Invention

The invention relates to seating arrangements and configurations forautomotive vehicles, and, in particular, to seating systems forflexible, comfortable and safe automotive travel.

2. Background Art

Comfort, convenience and versatility are at a premium for today's moderntraveler. Accordingly, the automotive industry has taken significantsteps to accommodate the evolving needs of its customers. Examples ofsuch recent improvements in the automotive world include multi-zoneclimate control systems, passenger entertainment modules, andinterior/exterior vision systems.

To meet the needs of its customers, the desire to provide seatsadaptable for various travel situations has emerged. Families and othergroups often compromise between the need for comfortable and convenientseating arrangements and storage. To accommodate the varying needsamongst potential customers, various seating systems have become knownin the art.

One such seating apparatus allows users to detach and remove a vehicleseat from the vehicle's interior to increase the amount of storage spaceavailable. The vehicle seat can then be returned to the vehicle shouldadditional seating capacity be needed. While the removable seatapplication provides increased versatility for hauling either a largeamount of cargo, or rather, a large family, inserting and removing suchseats can be a cumbersome task. Further, such seats are often limited intheir movement and adjustability within the vehicle. Generally, two ormore individuals are required to unlatch and remove the seat from thevehicle. Once removed, a storage location for the bulky seat is thenneeded when the seat can be kept clean and dry.

Other seating devices allow for the flexibility between additionalstorage and additional seating capacity without necessarily removing oneor more seats. For example, many vehicles have foldable seats whereinthe backrest can be folded forward towards the seat cushion when not inuse to provide additional cargo room. Generally, the folded seatcollapses to create a portion of a floor for a cargo area. Such seatsare popular in SUVs and vans, but have also been introduced into thebackseat of cars to access the trunk. While such seating devices areconvenient for rapidly alternating between extra cargo room and extraseating, they provide little versatility for varying the seatingconfiguration to adjust for a host of traveling situations.

Recent trends show that today's travelers have a greater need forflexibility in their automotive interiors. More individuals are takingtheir business on the road and spend a great deal of time in theirautomobile. Still others have young families they wish to take on longdrives, perhaps during a vacation. To better accommodate the needs ofthese travelers, more flexible seating arrangements and configurationsare in need. For example, nothing currently in production provides for aflexible, convenient, safe, and comfortable way to travel while stillallowing passengers to conduct business face-to-face. Further, familiesare not afforded the option of allowing their children to either faceforward or rearward, without concern over seat belt restraint mechanismsor unsafe air bag deployment.

The previous known seating systems are problematic with regard toflexibility convenience, safety, and/or comfort. The present inventionovercomes the above disadvantages by providing a unique and trulyversatile seating arrangement and configuration system that maintainscomfort and safety standards during vehicle operation.

DETAILED DESCRIPTION

Detailed embodiments of the present invention are disclosed herein.However, it is to be understood that the disclosed embodiments aremerely exemplary of an invention that may be embodied in various andalternative forms. Therefore, specific functional details disclosedherein are not to be interpreted as limiting, but merely as arepresentative basis for the claims and/or as a representative basis forteaching one skilled in the art to variously employ the presentinvention.

One aspect of the present invention is directed to an apparatus andsystem for providing a more flexible interior package for automotivevehicles described in greater detail below, the system, according to thepresent invention, allows vehicle passengers to readily adapt theirseating arrangement to be more conducive to practical travel situations,without compromising passenger comfort and safety. The ability of thesystem of the present invention to allow unique and versatile seatingoptions decreases the burden on passengers when traveling viaautomobile.

Referring generally to FIGS. 1 a-1 d, vehicle 10 having a flexibleinterior package in accordance with a certain embodiment of the presentinvention is illustrated. Vehicle 10 is preferably a sport utilityvehicle (SUV), van, or any such vehicle having at least three rows ofseats, but may also be included in a standard sedan-type vehicle.Vehicle 10 includes interior 12 comprised of front cabin 14, rear cabin16, and intermediate cabin 18. Front cabin 14 generally encompasses thearea of interior 12 nearest the instrument panel 13, while rear cabin 16generally encompasses the area of interior 12 nearest the rear ofvehicle 10. Correspondingly, intermediate cabin 18 generally encompassesthe area interposed between front cabin 14 and rear cabin 16.

Interior 12 further comprises first row seats 20 located within frontcabin 14. Preferably, at least two seats comprise first row 20.Typically, as shown in FIGS. 1 a-1 c, first row seats 20 face forwardtoward windshield 22 and are generally aligned laterally across vehicle10. In a certain embodiment, each seat in first row 20 is capable oftranslating linearly along the vehicle floor between a fore position,towards the front of vehicle 10, and an aft position, towards the rearof vehicle 10. It is therefore contemplated that any apparatus andmethod for providing horizontal travel of a vehicle seat between a foreposition and an aft position can be utilized in accordance with thepresent invention, such as is known in the seat track art. For example,International Publication No. WO 02/14103 A1 discloses such a seat trackarrangement, and is hereby incorporated by reference. An improved andunique seat track arrangement is also disclosed herein and describedsubsequently with regard to FIGS. 12 a-12 c.

Front cabin 14 is further defined by a forward boundary and a rearwardboundary. The forward boundary, for example, can be dashboard 13 or someother object generally defining a boundary between interior 12 and anengine compartment of vehicle 10. The rearward boundary, on the otherhand, is generally defined by the rearmost limit of a seat in first row20 when translated in the aft position.

Second row of seats 28 is generally located within intermediate cabin18. Preferably, at least two seats comprise second row 28. Morepreferably, three seats comprise second row 28. Second row 28 isgenerally parallel to and positioned behind first row 20, as depicted inFIGS. 1 a-1 c. In a certain embodiment, each seat in second row 28 iscapable of translating linearly along the vehicle floor between a foreposition, towards the front of vehicle 10, and an aft position, towardsthe back of vehicle 10, similar to first row 20. Again, it iscontemplated that any apparatus and method for providing horizontaltravel of a vehicle seat between a fore position and an aft position canbe utilized in accordance with the present invention. Further, therearmost limit of a seat in second row 28 when translated in the aftposition defines the boundary between intermediate cabin 18 and rearcabin 16.

Finally, third row of seats 30, generally located within rear cabin 16,is provided. Preferably at least two seats comprise third row 30. Morepreferably, three seats comprise third row 30. Third row 30 is generallyparallel to and positioned behind second row 28, as illustrated in FIGS.1 a-1 d. Like first row 20 and second row 28, each seat in third row 30may be capable of translating linearly along the vehicle floor between afore position, towards the front of vehicle 10, and an aft position,towards the back of vehicle 10. It is contemplated that any apparatusand method for providing horizontal travel of a vehicle seat between afore position and an aft position can be utilized in accordance with thepresent invention, such as is known in the seat track art. Further, rearcabin 16 is bounded to the rear by an object such as liftgate 17, or arear door, or possibly an additional row of seats. It is fullycontemplated that additional rows of seats can be provided withoutlimiting the scope of this invention.

Referring now to FIGS. 3 a-3 c, a seat 34 according to a certainembodiment of the present invention is illustrated. Reversible seat 34is generally comprised of seat cushion 36 and backrest 38. Seat cushion36 includes front portion 40, rear portion 42, upper surface 44, andlower surface 46. Seat cushion 36 is operatively coupled to supportingstructure 21. Front portion 40 is the portion of seat cushion 36 nearestthe front of vehicle 10, while rear portion 42 is the portion of seatcushion 36 nearest the rear of vehicle 10. Preferably, upper surface 44is contoured to provide lateral support, best shown in FIG. 4 a.Moreover, upper surface 44 is generally symmetrical such that frontportion 40 and rear portion 42 are substantially similarly contoured toallow an occupant to sit on seat cushion 36 and comfortably face eitherforward or rearward.

Backrest 38 is coupled to seat cushion 36 such that it is movablebetween a forward seating position (FIG. 3 a) and a rearward seatingposition (FIG. 3 c). The term seat cushion is used herein, but it shouldbe appreciated that the term is intended to include not only the cushionitself but all related structure such as the seat base, rail or anchor.When backrest 38 is adjusted in the forward seating position, adjoiningrear portion 42 of seat cushion 36, reversible seat 34 faces forward, asis illustrated in FIG. 3 a. When backrest 38 is adjusted in the rearwardseating position, adjoining front portion 40 of seat cushion 36,reversible seat 34 faces rearward, as illustrated in FIG. 3 c.Accordingly, backrest 38 has front face 48 and back face 50, may besubstantially similarly contoured and adapted to support an occupant'sback which rests thereupon. For example, an occupant in reversible seat34 is supported by front face 48 of backrest 38 when backrest 38 is inthe forward seating position. Alternatively, an occupant in reversibleseat 34 is supported by back face 50 of backrest 38 when backrest 38 isin the rearward seating position. Preferably, both front face 48 andback face 50 are contoured to provide lateral support. Therefore, anoccupant can comfortably rest in reversible seat 34 while facingrearward without foregoing any of the comfort normally obtained fromstandard non-reversible automotive seats.

Alternate constructions and designs of a seat back for use in thepresent invention are further disclosed in FIGS. 6 a-6 d when thesubstantial similar contour of the seat back is shown in detail. Asshown, the cross section of a seat back 38 include side lateral supports39 and center support 41. The lateral supports in 39 and center supports41 are disposed on both the front face 48 and back face 50 of the seatback 38. As can be appreciated by viewing FIG. 6 a, a desirable shapefor seat back 38 is contoured to provide lateral support when used inboth a forward and a rearward seating position. FIGS. 6 a-6 b alsodisclose lumbar support 96 is illustrated within backrest 38. Lumbarsupport 96 provides varying degrees of back support depending on thepreferences of a seat occupant. Lumbar support 96 can provide sufficientsupport to a user whether seated when backrest 38 is in the forwardseating position or rearward seating position. In a certain embodiment,lumbar support 96 comprises bladder 120 and pump and solenoid assembly122. The solenoid is electrically coupled to rocker switch 124 (shown inFIGS. 4 a-4 b). The depression of rocker switch 124 in one directionactivates pump and solenoid assembly 122, thereby inflating bladder 120.The inflation of bladder 120 causes both front face 48 and back face 50to extend outward effectuating support for occupants regardless ofwhether they face forward or rearward, as depicted in FIG. 6 b. Ofcourse, if less support is desired, a user merely depresses rockerswitch 124 in the opposite direction to relieve bladder 120.

FIGS. 6 c and 6 d provide an alternative arrangement for thesubstantially similarly contoured seat back 38 of FIGS. 6 a and 6 b. InFIG. 6 c, the back face 50 of the seat back 38 is substantially planar.However, front face 48 is appropriately contoured to provide lateralsupport for the occupant. The construction of the seat back 38 includesa center plate 51 with at least one airbag or bladder 53 a, 53 b and 53c disposed near the front face the bladders can be inflated to providethe appropriate contour for the front face 48. When in the rearwardseating position, illustrated in FIG. 6 d, the airbags 53 a, 53 b and 53c are substantially deflated disposed on the opposing side of the centerplate 51 is a second compliment of airbags 55 a, 55 b and 55 c which maybe inflated to provide a contour to the back face 50 while the seat isin the rearward seating position. It should be noted that the bladders53 and 55 can be automatically or manually controlled or adjusted by useof an electric motor.

Returning to FIG. 3 a, seating surface 52 is illustrated. Seatingsurface 52 is the surface created by seat cushion 36 and backrest 38 forsupporting an occupant when reversible seat 34 is facing forward.Accordingly, seating surface 52 is generally defined by upper surface 44and front face 48 of seat back 38 when backrest 38 is in the forwardseating position.

Seating surface 52′ is illustrated in FIG. 3 c. Seating surface 52′ isthe surface created by seat cushion 36 and backrest 38 for supporting anoccupant when reversible seat 34 is facing rearward. As such, seatingsurface 52′ is defined by upper surface 44 and back face 50 whenbackrest 38 is in the rearward seating position. Seating surface 52 issubstantially the mirror image of seating surface 52.

Seat 34 further includes headrest 54 affixed to the top of backrest 38.Preferably, headrest 54 is shaped and positioned to provide adequatesupport for an occupant's head whether backrest 38 is in the forwardseating position or the rearward seating position. Most preferably,headrest 54 is contoured such that it affords an occupant the samecomfort and safety regardless of which direction the occupant faces whensitting in reversible seat 34. Alternatively, headrest 54 may rotateabout the z-axis. For example, headrest 54 may include a single post 57extending therefrom. Post 57 may include a plurality of slots 59 forsetting the height of headrest 54. Post 57 is disposed to extend into anopening 61 in the seat back 38. Operatively coupled to the seat back 38is an engagement member 63 that is adapted for insertion into one ofsaid plurality of slots 59. The engaging member 63 is biased toward thepost 57 by a spring or other suitable structure so as to firmly maintainthe headrest 54 in position. It should be appreciated that post 57 canrotate about a z-axis in accordance with the arrow 167. It should alsobe appreciated that the plurality of openings 59 extend laterallythrough post 57 such that when headrest 54 is rotated 180° the engagingmember 63 may be also used to position the headrest 54 in the desiredheight position.

In a certain embodiment, generally illustrated in FIGS. 3 a-3 c,backrest 38 is slidably movable from a forward seating position to arearward seating position. Accordingly, backrest 38 is coupled eitherdirectly or indirectly (through a related structure) to seat cushion 36or base by a pair of seat brackets 56, one on either side of reversibleseat 34 (see FIG. 4 a or 4 b). Seat brackets 56 can be either fixedly orpivotally attached to backrest 38 at one end. At the other end, seatbracket 56 is affixed to a pair of laterally spaced guide members 58.Guide members 58 may contact the lower surface 46 of seat cushion 36.The opposing guide members 58 are spaced apart such that each guidemember generally runs below a corresponding side of seat cushion 36, asbest shown in FIG. 4 a. Each guide member 58 extends from first end 60to second end 62. First end 60 is positioned adjacent front portion 40,while second end 62 is positioned adjacent rear portion 42. Contactmembers 56 are slidably engaged with guide members 58 by use of asliding member 64 linking contact members 56 to guide members 58.Sliding member 64 can be a bearing, roller, or the like, that cansmoothly travel along guide members 58 from second end 62 correspondingto a forward seating position, to first end 60, corresponding to therearward seating position. FIG. 3 b depicts backrest 38 when slidingfrom the forward seating position to the rearward seating position atapproximately the half-way point of travel.

Guide members 58 can be an arcuate metal track, such as depicted inFIGS. 3 a-3 c, certain implementations of the present invention mayutilize a straight or linear metal track. In either instance, both firstends 60 and second ends 62 may include a locking member 65 for securingbackrest 38 in either the forward seating position or the rearwardseating position. Locking member 65 prevents backrest 38 from slidingalong guide members 58, when it is not desired to do so. Locking member65 can be a mechanical latch, tether, or the like. Certain lockingdesigns are illustrated in FIGS. 13 and 14. It should be appreciatedthat instead of using a guide member or related structure to translatethe seat back, the seat back may be selectively engageable at a forwardposition and a rearward position.

FIGS. 13 a-13 c illustrate a first locking design. As illustrated, theseat bracket 56 includes an action bolt 157 operatively connectedthereto. Preferably, the action bolt is formed in a bow-tie shape and ismovable from a first position (illustrated in FIG. 13 b) and a lockposition disclosed in (illustrated in FIG. 13 c). The action bolt 157may cooperate with a reinforced opening formed in the seat cushion 36,or alternatively, stiffening rods 163 formed as part of the seat.Further, it is also contemplated that the action bolt 157 may beattached to the seat cushion and cooperate with a mating hole formed inthe seat bracket 56. It also should be appreciated that although thelefthand side of the vehicle seat is illustrated, a similar apparatus ispreferably disclosed on the opposing side of the vehicle seat. Forsimplicity, however, only the lefthand side structure is disclosed indetail herein. It should also be appreciated that action bolt 157 maycooperate with a slot 65 formed in the seat frame structure 67 disposedbelow seat cushion 38.

An alternative locking mechanism could be accomplished by way of apivotable latch 69 and attachment bar 71 illustrated in FIGS. 14 a and14 b. The pivotable latch 69 is attached to the seat cushion or relatedstructure is disposed to move about a pivot pin 73 having a first leverhand 75 and a second locking hand 77. Second locking hand 77 is disposedto engage with attachment bar 71 to retain backrest 38 in the desiredposition. It should be appreciated that pivotable latch 69 can beactivated manually, or preferably, activated by electric motorautomatically when backrest 38 is in the desired forward or rearwardseating position.

Also disclosed in FIG. 13 a is an alternate sliding member 64construction. As illustrated, sliding member 64 can be constructed oftwo formations or rollers to facilitate ease of travel and support ofthe backrest.

Returning to FIG. 3, in another certain embodiment, reversible seat 34further comprises biasing member 67. Biasing member 67 is operablyconnected to guide members 58 to tilt or incline front portion 40 ofseat cushion 36 such that front portion 40 is positioned higher thanrear portion 42 when backrest 38 is in the forward seating position.Alternatively, biasing member 67 tilts rear portion 42 such that it ispositioned higher than front portion 40 when backrest 38 is in therearward seating position. Biasing member 67 comprises first pivotingcam 68 and second pivoting cam 70. First pivoting cam 68 is coupledbetween the first ends 60 of guide members 58, while second pivoting cam70 is coupled between the second ends 62 of guide members 58. Both firstpivoting cam 68 and second pivoting cam 70 are generally verticallybiased by a spring, coil, or D.C. motor. When sliding member 64 reachessecond end 62 of guide member 58, the vertical bias of second pivotingcam 70 is overcome such that second pivoting cam 70 is caused to berotated to a more horizontal position, as shown in FIG. 3 a. Preferably,sliding member 64 contacts and releases the spring, coil, or D.C. motorthat vertically biases the second pivoting cam 70. It should be notedthat the D.C. motor used for biasing the pivoting cams 68 and 70 canalso be used to provide power to translate the vehicle seat fore and afton the vehicle floor. Moving sliding member 64 away from second end 62while transitioning backrest 38 from the forward seating position towardthe rearward seating position, second pivoting cam 70 returns to itsvertically biased position. Once sliding member 64 terminates in firstend 60 of guide member 58, the vertical bias of first pivoting cam 68 isovercome, causing first pivoting cam 68 to rotate toward a generallyhorizontal position, as illustrated in FIG. 3 c. Accordingly, firstpivoting cam 68 aligns front portion 40 of seat cushion 36 slightlyabove rear portion 42 when backrest 38 is moved to the forward seatingposition. Correspondingly, second pivoting cam 70 aligns rear portion 42of seat cushion 36 slightly above front portion 40 when backrest 38 ismoved to the rearward seating position.

Preferably, second row 28 comprises a plurality ofreversible seats such that each reversible seat 34 can be adapted toface third row 30. In this embodiment, occupants in second row 28 faceoccupants in third row 30 facilitating face-to-face communications andeasing interaction therebetween. For example, passengers traveling forbusiness purposes can conduct meetings or conferences, while a drivertakes them to their destination. Table 98 can be erected between secondrow 28 and third row 30 to enhance productivity by providing a surfaceby which to rest business papers or other work materials. In thisembodiment, table 98 is similar to a conference table. As anotherexample, families traveling on long road trips, such as during avacation, may want to create an area for children to interact with oneanother. If desired, families could use table 98 to have a family mealduring a trip. In this embodiment, table 98 is similar to a café table.In a certain embodiment, table 98 includes table base 100, which isreceived by a receptacle in the floor of vehicle 10, affixing table 98thereto. Alternately, table 98 may not include a base, but rather isattachable to the sides of interior 12 such that it is supportedlaterally across interior 12 from one side to the other by projections15 formed on the indoor walls. It is fully contemplated that there aremany other reasons and uses for second row 28 to be adapted to facethird row 30, such as common viewing of an entertainment system placedon the side wall of the vehicle in accordance with the teachings of thepresent invention. Further, the uses suggested for table 98 are merelyexemplary, and it is contemplated that alternate uses are available.

Referring now to FIG. 1 c, the at least one seat 34 is located in thirdrow 30. Accordingly, the at least one reversible seat 34 can be adaptedto face rearward such that occupants in third row 30 can peer out therear of vehicle 10.

Although the at least one reversible seat 34 is shown and described ineither first row 20, second row 28 or third row 30, it is fullycontemplated that the at least one reversible seat 34 can be located infirst row 20, second row 28 and third row 30. Moreover, it is preferablethat each seat in vehicle 10 comprises reversible seat 34.

Although reversible seat 34 provides for flexible seating within vehicle10 for a multitude of travel situations standard on most vehicles todayare airbags, both for driver and passenger, to protect in the event of acollision. These airbags are designed to be deployed when an occupant isfacing forward toward the front of a vehicle. It may be unnecessary todeploy an airbag while an occupant faces rearward. Accordingly, eachreversible seat 34 is equipped with airbag deactivation device 106.Airbag deactivation device 106 enables an airbag to be deployed uponcollision when backrest 38 of reversible seat 34 is in the forwardposition. However, when reversible seat 34 is adjusted such thatbackrest 38 is in the rearward seating position, airbag deactivationdevice 106 disables the airbag. Airbag deactivation device 106 controlsonly the airbags corresponding to the reversible seat 34 to which thedevice is attached, but may be designed to correspond to a multitude ofseating arrangements. Moreover, it is contemplated that airbagdeactivation device 106 can enable one or more airbags, while disablingone or more other airbags, when reversible seat 34 is in the forwardseating position. Upon adjusting reversible seat 34 to the rearwardseating position, the previously enabled airbags become disabled, whilethe previously disabled airbags become enabled.

Airbag deactivation device 106 can be any device that senses theposition of backrest 38 and can differentiate between backrest 38 beingin the forward seating position or the rearward seating position, suchas a limit switch or a proximity sensor, or the like. Airbagdeactivation device 106 then sends an appropriate signal to the controlunit of the airbag enabling or disabling the airbag. Airbag deactivationdevice 106 can be used in conjunction with seat locking device 104 tosend signals to the appropriate modules. Moreover, it is contemplatedthat seat locking device 104 is the same as airbag deactivation device106.
